Generalized Label for Super-Channel Assignment on Flexible Grid draft-hussain-ccamp-super-channel-label-03 IETF 83 - Paris, France March , 2012 Iftekhar Hussain Abinder Dhillon Zhong Pan Marco Sosa Bert Basch Steve Liu Andrew G. Malis

Agenda Changes since IETF-82 Open Issues Next Steps draft-hussain-ccamp-super-channel-label-03

Changes Ver-02 to Ver-03 Modified – Changed the term “group” to “slot” in the n_start and n_end fields in the label Added (similar to RFC4328) a new G-PID type = OTUadapt » See (ITU-T SG15, Contribution C1573r1, Dec 2011 (Geneva)) a new G-PID value to be assigned by IANA A new Switching Type = Super-Channel-Switch-Capable(SCSC) » See draft-dhillon-ccamp-super-channel-ospfte-ext) LSP Encoding Type = Lambda (as defined in RFC4328) draft-hussain-ccamp-super-channel-label-03

Proposal - Summary Extends [RFC3471] [RFC6205] – Defines a new generalized label format for super- channels assignment on flex-grid networks Super-Channel Label extensions summary – Allows label assignment for both Contiguous Spectrum and Split-Spectrum Super-Channels – Provides two encoding options for the label List/Range (n_start, n_end) Bitmap draft-hussain-ccamp-super-channel-label-034

Open issues Terminology clarifications – Framework document submitted with definitions & use cases WG agreement on Control Plane requirements – Alignment with ITU docs on data plane aspects draft-hussain-ccamp-super-channel-label-03

Super-Channel Optical Parameters GMPLS Signaling Extensions draft-hussain-ccamp-super-channel-param-sig-00 IETF 83 - Paris, France March , 2012 Iftekhar Hussain Vinayak Dangui Michael Marco Sosa

Agenda Motivation Extensions Summary TLV Summary Use Case Open Issues Next Steps draft-hussain-ccamp-super-channel-param-sig-00

Motivation Coexistence of super-channels using different modulation formats Adjacent super-channels may affect each other detrimentally Desirable to evaluate the mutual impact of the existing and new super-channels on each other's quality of transmission draft-hussain-ccamp-super-channel-param-sig-009

Extensions Summary This draft defines GMPLS signaling extensions to convey following super-channel optical parameters: – Number of Carriers – Carrier Center Frequency (THz) – Carrier Modulation – Carrier Baudrate (Gbit/s) – Carrier FEC Type 10draft-hussain-ccamp-super-channel-param-sig-00

TLVs Summary Defines following new TLVs – Super-Channel Carriers TLV Carrier sub-TLV Carrier – Carrier Center Frequency sub-sub-TLV – Carrier Modulation sub-sub-TLV – Carrier FEC sub-sub-TLV Two options to carry these TLVs – Option 1 RSVP FLOWSPEC or TSPEC Object – Option 2 (add in next revision) With the Super-Channel Label draft-hussain-ccamp-super-channel-param-sig-0011

Super-Channel Carrier TL and Sub-TLVs draft-hussain-ccamp-super-channel-param-sig-0012

Carrier Center Frequency, Modulation, and FEC sub-sub-TLV 13draft-hussain-ccamp-super-channel-param-sig-00

Use Case Signal optical parameters of the super-channel in the RSVP message using proposed TLVs Each node along the super-channel setup path allocates the required number of slices and learns the associated set of signaled parameters. Each node advertises this information to other nodes in the network using routing extensions (see draft-hussain-ccamp-super-channel- param-ospfte) to apply added constraints 14draft-hussain-ccamp-super-channel-param-sig-00
